• r8712u = Flaky Wireless?


    I replaced a flaky wireless adapter on the family desktop, but the new one seems a bit wonky as well. i think it may b due to the choice of driver. here’s what we have:

    *-usb
    description: Wireless interface
    product: RTL8188S WLAN Adapter
    vendor: Manufacturer Realtek
    physical id: 5
    bus info: usb@5:5
    logical name: wlp0s19f2u5
    version: 2.00
    serial: 00e04c000001
    capabilities: usb-2.00 ethernet physical wireless
    configuration: broadcast=yes driver=r8712u maxpower=500mA multicast=yes speed=480Mbit/s wireless=IEEE 802.11bgn

    Is there something else i should be using instead of the r8712u driver for this RTL8188s adapter?

    thanks

  • If there is a certain USB wireless adapter you guys can recommend that works flawlessly out of the box, that recommendation is welcome too.

  • R8712u is a Realtek driver. These drivers are close sourced, meaning the community can’t improve the driver nor the firmware (needed to run some devices as well). The best brand, which has open-source driver and thus better support in general under Linux is ‘Atheros’.

    So pick a wifi adapter with Atheros chipset, which using the ath9k_htc driver.

    Check-out this wiki page for example:

  • It can’t hurt to give this one a try :expressionless:
